WINDOW-SCREEN.

Application filed June 23, 1917.

To all whom it may concern.

Be it known that we, FRANK HAUS and JOHN PANGNER, both subjects of Hungary, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in lVin- (low-Screens, of which the following is a specification.

This invention relates to window screens of that type in which a screen is mounted on a roller on the window casing and attached to the lower bar of the sash, so that when the window is raised the screen will be extended and when the sash is lowered the screen will be taken up by the spring roller.

The object of the invention is to improve and simplify such construction and to provide an improved form of screen fabric.

In the drawings:

Figure 1 is an elevation with the sash closed;

Fig. 2 is a similar view with the sash open;

Fig. 3 is a central vertical section of Fi 2- Fig. 4c is a longitudinal section through one end of the screen housing;

Fig. 5 is a detail in perspective of the screen housing and roller in supported position.

In the drawings, 1 indicates a window frame, 2 the guide strips and 3 the sill. 1 is a screen. This screen consists of a flexible rubber sheet with many perforations therein, and to one end of this is attached a hard rubber strip 5 with holes 6 therein to receive hooks T on the lower bar of the sash, whereby the screen is attached thereto. The other end of the screen is fastened to an ordinary spring shade roller 8 which is mounted in the casing 9 which is secured to the sill. This casing consists of a front wall 11, a top wall 12 and end pieces 10 and is conveniently fastened to the sill by screws through lugs 13 on the front wall. The end pieces 10 have dove-tailed grooves in- Specification of Letters Patent.

dicated at 14, which receive the dove-tailed blocks 15 which hold the roller 8. These blocks have slots 16 to receive the pintles 17 of the roller. By these devices the roller and screen may be placed completely within the housing without any of the parts projecting. The open side of the housing is toward the sash, and the edges of the screen 4 lie within the guide' ways of the sash, closely adjacent the guide strips 2.

Obviously, when the sash is raised the screen will be extended or elevated, and when the sash is lowered the spring roller will take up the screen within the housing.

The perforated rubber screen is serviceable and durable and will easily wind on the roller.

lVe claim:

1. In a window screen, the combination of a housing, blocks removably fitted in the ends of the housing, a roller mounted within the blocks and a flexible screen attached to the roller and adapted to be connected to the window sash.

2. In a window screen the combination of a housing having grooved ends, a pair of blocks fitted in the grooves, a spring roller mounted between the blocks, and a flexible screen connected to the roller at one end and adapted to be connected tothe sash at the opposite end.

3. The combination with a window casing and sash, of a spring roller mounted on the casing, a sheet of flexible screen material connected at one end to the roller and having a strip across the other end provided with holes, and hooks on the sash engageable in said holes.

In testimony whereof, We do affix our signatures in presence of two witnesses.
